[ANN]: 'tsshbatch', Batch ssh Tool, Version 1.137 Released
by Tim Daneliuk 23 Feb '13

23 Feb '13

'tsshbatch' Version 1.137 is now released and available for download at: http://www.tundraware.com/Software/tsshbatch WHATSNEW For 'tsshbatch' 1.137 (Fri Feb 22 15:30:24 CST 2013) ---------------------------------------------------------------------- - Changed error reporting to place the entire message on a single line. - Changed the manner of error reporting to provide more specific detail. The original error messages could be misleading because both the inability to connect and an ssh rejection reported the exact same error. What Is 'tsshbatch'? ------------------ 'tsshbatch' is a tool to enable you to issue a command to many servers without having to log into each one separately. When writing scripts, this overcomes the 'ssh' limitation of not being able to specify the password on the command line. 'tsshbatch' also understands basic 'sudo' syntax and can be used to access a server, 'sudo' a command, and then exit. 'tsshbatch' thus allows you to write complex, hands-off scripts that issue commands to many servers without the tedium of manual login and 'sudo' promotion. System administrators, especially, will find this helpful when working in large server farms. 'tsshbatch' is written in Python and requires the 'paramiko library. It has been tested on various Linux and FreeBSD variants as well as cygwin on MS-Windows. --------------------------------------------------------------------- Complete details of all fixes, changes, and new features can be found in the WHATSNEW.txt and documentation files included in the distribution. A FreeBSD port has been submitted as well.

22 Feb '13

Hi, Firebase (www.firebase.com) is a scalable real-time backend that stores your data in a JSON format and enables you to fetch/update/delete it through a Javascript or RESTful API. I've just implemented a Python interface to its REST API while using it in one of my projects. If you'd like to use it, you can check that out at my github repository. http://ozgur.github.com/python-firebase/ Cheers.

Free PyCon 2013 passes!
by Wingware 20 Feb '13

20 Feb '13

Hi, Wingware is a Gold Sponsor at PyCon 2013 and we have three conference passes that we are looking to give away. The conference is completely sold out, and these passes are a hot commodity, so we thought we would have some fun with this, rather than just offering them on a first-come-first-served basis as we usually do. Here is the deal: To apply for a free pass, in five paragraphs or less, tell us about ONE of the following: 1) How and why you use Wing IDE, and what it has allowed you to do that you could not have done without it. 2) How and why you use Python, where it shines, and how it has inspired and empowered you. 3) Tell us something really interesting, funny, or inspiring that you have worked on or experienced as a programmer, or just as a human. The authors of three best entries will be given the free PyCon 2013 passes. Submissions must be emailed to sales(a)wingware.com by 11:59pm PST Friday February 22nd and we will choose the three winners over the following weekend. Here's the catch: You must be willing to allow us to use the text that you submit on our website and/or blog. We hope to publish the winning entries on our blog, but reserve the right not to, depending on the content of the entries. ;-) Please be sure to check the feasibility of traveling to the conference before applying. We are offering only the conference passes and not any travel or lodging expenses. Thanks, -- Stephan Deibel Wingware | Python IDE Advancing Software Development www.wingware.com

ANN: pyftpdlib 1.0.0 released
by Giampaolo Rodolà 19 Feb '13

19 Feb '13

Hi there guys, After 1 year of development and refinements I'm pleased to announce a release of pyftpdlib which appears to be the fastest FTP server out there (on UNIX at least)! See: http://code.google.com/p/pyftpdlib/wiki/Benchmarks 1.0.0 release introduces serious improvements amongst which python 3 support (finally!) and full Unicode support. Here's the major ones. === New IO loop and epoll() / kqueue() support === The IO loop, originally relying on asyncore, has been rewritten from scratch (http://code.google.com/p/pyftpdlib/source/browse/trunk/pyftpdlib/ioloop.py) and now supports epoll() on Linux and kqueue() on OSX/BSD. Also select() (Windows) and poll() pollers have been rewritten resulting in pyftpdlib being an order of magnitude faster and more scalable than ever. Read the full story here: http://code.google.com/p/pyftpdlib/issues/detail?id=203 === Alternative concurrency model === It is now possible to change the default concurrency model from async (non blocking) to multiple processes / threads based, meaning you are now free to block as long as you want and support particularly slow filesystems. Switching is as easy as changing an import. More information are here: http://code.google.com/p/pyftpdlib/wiki/Tutorial#4.6_-_Changing_the_concurr… === Python 3 porting + full Unicode support === Finally! === Logging === logging module is now used for logging as replacement for log(), logline() and logerror() functions which are now deprecated. Also, the whole logging infrastructure has been refactored and it is more compact and consistent. Also by default pyftpdlib logs will have colors. === Other improvements === * a new FilesystemError exception class is available in order send custom error strings to client from an AbstracteFS subclass. * on_connect() and on_disconnect() callbacks * FTPHandler.ftp_* methods implementing filesystem-related commands now return a meaningful value on success (tipically the path name). * FTPServer.serve_forever() has a new handle_exit parameter which can be set to False in order to avoid handling SIGTERM/SIGINT signals. === Backward compatibility breakage === A lot of backward incompatible changes have been introduced amongst which the different import system, the different validate_authentication() signature and the fact that the filesystem class now expects Unicode strings rather than bytes. HISTORY file enlists all of them and also provides a guide on how to port your existent to this new version. http://code.google.com/p/pyftpdlib/source/browse/trunk/HISTORY?spec=svn1175… === Some links === Home: http://code.google.com/p/pyftpdlib/ Download: http://code.google.com/p/pyftpdlib/list/downloads Tutorial: http://code.google.com/p/pyftpdlib/wiki/Tutorial Complete list of changes: http://code.google.com/p/pyftpdlib/source/browse/trunk/HISTORY That should be all folks. I hope you'll enjoy this new version, Giampaolo Rodola'

Nanpy 0.8 - Use your Arduino board with Python
by Andrea Stagi 19 Feb '13

19 Feb '13

Hi, Nanpy is growing faster, 0.8 is out!! It contains a lot of bugfixing and EEPROM support :) A lot of people is writing me about the project, send their experience, examples, bugfixing, ideas and I've also found two cool projects made using nanpy on Instructables.com - http://www.instructables.com/id/Arduino-Raspberry-Pi-Internet-Radio/ - http://www.instructables.com/id/Flight-Simulator-with-Arduino-and-Python/ Amazing! I'm really happy, thank you guys :) We also have a repository with some projects made using Nanpy: https://github.com/nanpy/eggsamples ... if you have a project made with Nanpy and it's open source please let us know!! :) Enjoy Nanpy and discover its simplicity expecially using it with a RaspberryPi.. in the last MagPi issue I explain how to accomplish that: http://www.themagpi.com/ Remember that Nanpy is now an organization on Github! Join us and/or donate if you like it! https://github.com/nanpy WHAT IS NANPY -------------------- Nanpy is a pure Python library that allows you communicating with an Arduino board connected via USB. Classes and methods used are really similar to the Arduino framework's ones, but simpler and with some additional features, so people who haven't worked with an Arduino can be easily introduced to his world.. The main purpose of Nanpy is making developers' life easier, giving them something simple and fast to use to create prototypes and scripts interacting with Arduino, saving time and making them concentrate on the problem. There are a lot of projects able to do something similar, using Python or other languages, but Nanpy can do more! Nanpy is easily extensible and can theoretically use every library Arduino supports, allowing you to create how many objects you want and without worrying about deallocation. Also, you can use Nanpy in parallel and concurrence programs. Nanpy is under heavy development but is growing fast and just supports the main methods of OneWire, Lcd, Tone, DallasTemperature, Stepper and Servo libraries. Just a word of warning: Raspberry Pi may not provide enough power to drive an Arduino, so you might need external power. UNDER THE WOOD ------------------------ With Nanpy you can write your Arduino programs using Python, communicating via serial port without sending hard-to-remember codesor limiting you to use only one object: when you create an object in Python it will be automatically created into your Arduino at runtime.. For example if you write something like Arduino.pinMode(13, Arduino.OUTPUT) Arduino.digitalWrite(13, Arduino.HIGH) or tone = Tone(13) or lcd = Lcd([7, 8, 9, 10, 11, 12], [16, 2]) lcd.printString("Hello World!") or ds = DallasTemperature(5) Nanpy creates the correct object into Arduino for you.. Also, you haven't to take care of deallocation, Nanpy deallocates objects into Arduino as soon as the correspondent Python objects get deleted. Look at the examples to see how simple it is.. (https://github.com/nanpy/nanpy/tree/master/examples) :) I tried running Nanpy on a Raspberry board and it works great!!(that's the result from one of my friends' Twitter account https://twitter.com/andreagrandi/status/251702684380434434 :) ). Also you can use it in other devices suppoting Python and serial communication, with Django, for creating prototypes faster etc.. because you use Python and you don't have to flash the firmware every time. Last but not least, firmware part of Nanpy is Python-indipendent, so you can write another implementation of Nanpy in any other language, for example Java, and see an Arduino controlled via Android (ok, in this case we should use Android USB Host API, writing our own driver, because Android doesn't provide anything to access device files). We will work on this in the future :) DONATE ----------- Do you like Nanpy? Contributions/suggestions/bug reporting/spreading the project/beers/coffee are accepted :) if you want to donate a coffee and be sure that we will work during the night, here's the link https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=TDTPP5… Thanks for your attention!

A new webpage promoting Compiler technology for CPython
by Travis Oliphant 15 Feb '13

15 Feb '13

Hey all, With Numba and Blaze we have been doing a lot of work on what essentially is compiler technology and realizing more and more that we are treading on ground that has been plowed before with many other projects. So, we wanted to create a web-site and perhaps even a mailing list or forum where people could coordinate and communicate about compiler projects, compiler tools, and ways to share efforts and ideas. The website is: http://compilers.pydata.org/ This page is specifically for Compiler projects that either integrate with or work directly with the CPython run-time which is why PyPy is not presently listed. The PyPy project is a great project but we just felt that we wanted to explicitly create a collection of links to compilation projects that are accessible from CPython which are likely less well known. But that is just where we started from. The website is intended to be a community website constructed from a github repository. So, we welcome pull requests from anyone who would like to see the website updated to reflect their related project. Jon Riehl (Mython, PyFront, ROFL, and many other interesting projects) and Stephen Diehl (Blaze) and I will be moderating the pull requests to begin with. But, we welcome others with similar interests to participate in that effort of moderation. The github repository is here: https://github.com/pydata/compilers-webpage This is intended to be a community website for information spreading, and so we welcome any and all contributions. Thank you, Travis Oliphant

[ANN] pypiserver 1.1.0 - minimal private pypi server
by Ralf Schmitt 15 Feb '13

15 Feb '13

Hi, I've just uploaded pypiserver 1.1.0 to the python package index. pypiserver is a minimal PyPI compatible server. It can be used to serve a set of packages and eggs to easy_install or pip. pypiserver is easy to install (i.e. just 'pip install pypiserver'). It doesn't have any external dependencies. http://pypi.python.org/pypi/pypiserver/ should contain enough information to easily get you started running your own PyPI server in a few minutes. The code is available on github: https://github.com/schmir/pypiserver Changes in version 1.1.0 ------------------------ - implement multi-root support (one can now specify multiple package roots) - normalize pkgnames, handle underscore like minus - sort files by their version, not alphabetically - upgrade embedded bottle to 0.11.6 - upgrade waitress to 0.8.2 in the standalone script - merge vsajip's support for verify, doc_upload and remove_pkg -- Cheers Ralf
